The structure and self-regeneration performance of Salix psammophila-activated carbon modified by Ag and N co-doped TiO₂

Abstract

In this study, Salix psammophila activated carbon (AC) was modified by immersing it in an AgNO3 solution and coating it with an N-doped TiO2 film to improve its self-regeneration performance in visible light.

Effect of Process Parameters on the Microstructure and Performance of TiO2-Loaded Activated Carbon

“…Moreover, this doping modification only aimed to enhance the photo-catalytic activity, while the adsorption performance of TiO 2 / AC is weakened in most cases. According to the previous studies, the regeneration performance of TiO 2 /AC is mainly determined by its adsorption and photocatalytic properties, 11,12 where the properties show a tight relationship with the microstructure of samples. On the one hand, the pore structure and surface chemistry structure are considered to be the key factors affecting the adsorption property of TiO 2 /AC.…”

Selective adsorption of metal ions on Salix psammophila fibre activated carbon

“…At 2θ = 37.76°, 43°, 64.38°, and 77.46°, the refraction maxima correspond to (111), ( 200), (220), and (311) crystal planes and belong to the graphite plane peak (Liu and Lang 2020). All three materials showed graphite plane peaks, which are the characteristic diffraction peaks of the crystal surface structure of carbon.…”

“…It is a natural porous material commonly used as a base material for activated carbon (Li et al 2014). Therefore, it is used to prepare activated carbon and used to improve the capacity of sewage treatment (Liu and Lang 2020). Secondly, by changing the adsorption capacities of adsorbents for different metal ions to achieve optimal selective adsorption effect, the sustainable development of resources is important (Kuroki et al 2019).…”
